This delivery will be the 23rd for NASA since the shutting down of the shuttle program in 2011. Since that time, NASA cargo has been transported by private companies.
Microscopic wars are constantly raging around, inside and inside us, as bacteria fight for resources and space. In the process, they have developed ingenious weapons such as tailocins that act against enemies like homing missiles. Scientists believe that we will be able to use them in the interests of humanity.
The Great Mojave Desert whispered something in the dark as Mad Mike prepared to fly. Mike Hughes and his old friend and like-minded Waldo Stakes, like many others, were brought to California by a dream. However, this dream was of a very special kind: to get to space in a homemade steam-powered rocket.
Soon, rocket flights into space will seem as bizarre as traveling long distances in a sleeping car. Of course, the rockets will be preserved for long flights — for example, to other planets — but we will get to orbit exclusively by elevator. The starting point will be a giant floating platform at the equator, from where passengers will be picked up by an elevator, which will take off into the sky at a speed of about 2000 km/ h. The first stop will be a space platform, where passengers will already feel weightlessness. It will hang in space at an altitude of about 35,000 km above ground level. Balancing the structure will be an asteroid, which is still about 10,000 km away. We have just briefly outlined the idea of a space elevator.
What would the four types of rockets look like at the start and during the separation of the stages if their body were made of transparent material? Fascinating!
Glue accounts for less than a percent of the mass and about 5% of the cost of complex machines — cars, computers, smartphones, airplanes, space rockets. But without glue, all of the above cannot be assembled — at least in our usual compact form. The PM correspondent visited the headquarters of Henkel in Dusseldorf — the world leader in the market of adhesive technologies - and found out why our life without glue would be much harder than it is.
Colonization of Mars is one of the most promising areas of the modern space industry. However, the biggest problem will not be rockets or life support systems, but the people themselves, whose bodies will have to adapt to new conditions.
Canadian scientists have questioned the popular hypothesis that the death of the famous expedition was the result of poisoning of sailors with lead, which in the middle of the XIX century was used for tinning cans.
Despite the improbability of a full-scale nuclear war, unfortunately, it cannot be completely ruled out. Contrary to everyone's hopes, this possibility does not decrease with time, and it is better to remember what to do in a nuclear explosion if you have a few hours, minutes or even seconds at your disposal.
